DETAILED DESCRIPTION
[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.
[0021] The present application provides an asphalt coil sand pressing device, such as Figure 1-Figure 4 As shown, it includes a vertical support rod 1, a first traction roller 4, a pushing mechanism, etc.
[0022] Specifically, the vertical support rods 1 are a pair, which are arranged at intervals on a base plate 101. The top of the vertical support rods 1 is hinged with a connecting rod 2, and a fixed seat 201 is provided at the bottom of the connecting rod 2. A sand pressing roller 3 is rotatably connected between the two fixed seats 201; the first traction roller 4 is provided below the sand pressing roller 3. When the connecting rod 2 rotates toward the first traction roller 4 to be perpendicular to the vertical support rod 1, the sand pressing roller 3 is directly above the first traction roller 4, and there is a preset distance between the sand pressing roller 3 and the first traction roller 4; the pushing mechanism is connected to the connecting rod 2 for driving the two connecting rods 2 to rotate synchronously.
[0023] During actual use, the asphalt coil 11 is passed between the sand pressing roller 3 and the first traction roller 4, and the pushing mechanism is controlled to drive the connecting rod 2 and the sand pressing roller 3 to rotate downward to compact the asphalt coil 11. Then, the first traction roller 4 is controlled to rotate to drive the asphalt coil 11 to move and compact the gravel on the asphalt coil 11, which can adapt to the sand pressing of asphalt coils 11 of different thicknesses.
[0024] For details, see Figure 1 In one embodiment, the pushing mechanism includes two first cylinders 5, the telescopic ends of the two first cylinders 5 are respectively hinged to the ends of the two connecting rods 2 away from the vertical support rod 1, and the fixed ends of the two first cylinders 5 are hinged to a bottom plate 101. By controlling the synchronous extension or retraction of the telescopic ends of the two first cylinders 5, the two connecting rods 2 can be driven to rotate synchronously, thereby driving the sand pressing roller 3 to rotate. In another embodiment, refer to Figure 2-Figure 4 The pushing mechanism includes a second cylinder 6 and a connecting shaft 7. The connecting shaft 7 is rotatably connected between the two connecting rods 2. The telescopic end of the second cylinder 6 is hinged to the middle of the connecting shaft 7. A fixing frame 102 is provided above the bottom plate 101. The fixed end of the second cylinder 6 is hinged to the fixing frame 102. When the distance between the first traction roller 4 and the sand pressing roller 3 needs to be adjusted, the telescopic end of the second cylinder 6 can be controlled to push out or retract. Moreover, through this setting, only one second cylinder 6 is required to drive the two connecting rods 2 to rotate synchronously. Compared with the synchronous rotation of the connecting rods 2 driven by two first cylinders 5, it can avoid the situation where the telescopic ends of the two first cylinders 5 are pushed out asynchronously or the pushed-out lengths are not uniform, which causes the sand pressing roller 3 to tilt.
[0025] For details, see Figure 1 A second traction roller 9 is spaced above the sand pressing roller 3, and guide rollers 10 are provided on both sides of the second traction roller 9. During sand pressing, the asphalt coil 11 passing between the sand pressing roller 3 and the first traction roller 4 is wound from above one guide roller 10 to below the second traction roller 9, and then wound again to above the other guide roller 10. This ensures that the asphalt coil 11 can be transported in coordination with the first traction roller, improving the stability of the asphalt coil 11 during transport.
[0026] Preferably, see Figure 2A water pipe 8 is disposed transversely on the side of the vertical support 1 away from the first traction roller 4. Multiple atomizing water spray pipes 801 are arranged axially around the circumference of the water pipe 8, with the water outlets of the atomizing water spray pipes 801 facing the circumference of the first traction roller 4. Spraying water onto the asphalt coil 11 through the atomizing water spray pipes lowers the surface temperature of the asphalt coil 11, thereby firmly adhering to the surface of the asphalt coil 11 and preventing the sand from sticking to the roller.
[0027] The above are only some of the embodiments listed in this application and are not intended to limit this application.
